If you are not familiar with vi, install and try the vimtutor application, which (as its name suggests) can teach you how to use the editor. If you have a different editor you like, such as Jove, Jed, Joe or emacs, you can install and use one of those.

Now, for the convenience of this demo app, you can just use the shell’s heredoc function, which allows you to type text directly into your gear:

To make your server visible to others, you can disable Flask’s debugging mode by adding –host=0.0.0.0 to the run command. This opens up ports on your phone, so use that.

Your phone may not be the perfect hub for a serious web app, but it goes to show that the possibilities are endless. Maybe you design on your Android device because it’s a great way to stay in shape, or you have a new passion for local web apps, or maybe you use a Flask app for your apps. Work every day.

Popular web hosts like HostGator and Godaddy offer cheap servers for hosting web applications.

Local web servers can be easily built for testing and programming with XAMPP and WAMP among the most popular web server packages for PC, but you can get the same features on Android. The best software for the job is Palapa web server, which gives you MySQL, PHP and Lighttpd pre-installed in one free hosting package, although be careful when trying to run it on a local server somewhere.
